Thanks for the report,

it was <istream> include missing with clang/libc++
Please run svn update it should work now.

Also once you build please don't forget to run "make test" or "ctest"
to get all the tests running on Mac OS X. (I don't have one to run on)
and it is forbidden to run one on non-Mac VM (according to Mac OS X EULA)

Ok thanks! I will dive into that.

Just curious, what would you use instead of signal2 in this case?

Take a look on description of Server Sent Events:

http://www.w3.org/TR/eventsource/

It is required for the client to automatic synchronization with the server
in case of disconnect.

Depends...

1. If the exception is thrown from cppcms::application::main (i.e.
request handler)
it would be wrtten into log (of course if logging enabled)
2. If it is thrown in the event loop thread - outside of ordinary
request it would propagate
all the way outside cppcms::service::run()

That is what mailing list for :-)

I think boost::signal(2) is good for "broadcasting" a signal to
multiple listeners
it is less interesting in case of one event sent to a specific target I'd just

Hi Artyom,

Thank you for your quick response. That really did the trick!

I have two other questions:
1) How does the "id" work under water? Is it that I just always need the id
and can add any data underneath it?
2) How does cppcms handle exceptions? For instance I have an Ajax-call to a
method and that method throws, but it seems that the exception is swallowed
somewhere as it does not appear anywhere?

Kind regards,
Eric

Ps. A nice comet-example with signals2 might be applicable for others as
well.

Re: [Cppcms-users] Server

[Artyom B. <art...@gm...>]

Hi,

You have two issues:

1st of all your code does not compile because sig.connect tries to
copy the ticker class which isn't something you actually want. And in
general if you already using boost::signals2 you should also use its
automatic disconnection handling. So first change would be

    boost::signals2::scoped_connection conn;

    void connectSlot()
    {
        conn = std::move(sig.connect([this](double v) {
                this->on_new_value(v);
        }));
    }

Now the second issue is that you should be aware of the fact that the
robot thread and application thread are different so what you need to
do is to use service().post(handler) to post code execution to the
main event loop of the cppcms:

   void on_new_value(double v)
    {
            service().post([=]() { // post for execution in relevant thread
                    this->handle(v);
            });
    }
    // now actual work
    void handle(double new_one)
    {
        cout << "SLOT CALLED" << endl;
        counter_++;
        price_ = new_one;
        for(auto waiter : waiters_) {
            async_send(waiter);
        }
        waiters_.clear();
    }

  Artyom

[Cppcms-users] Server

[eric m. <mid...@gm...>]

Hi,

I'm developing a robot that is controlled via the browser by issuing
commands.

Apart from the cppcms applications that are started from main, the server
has an additional thread for controlling the motors: robotThread

While the robotThread is acting on a command I like it to report progress
back to the browser so that I can follow what exactly it is doing.

The idea is to use ticker-example http://blog.cppcms.com/post/107 and
replace the timed updates by something like a boost::signals2 slot so that
progress in the robotThread can be reported to the cppcms comet application
that can report it to the browser.

Enclosed is the sourcecode of a small testprogram based on the ticker
example. It does not compile because of an error: use of deleted function
‘ticker::ticker(const ticker&). I can't find a way to connect the cppcms
comet application to the signal.

Do you have any idea how to do this or any other way to use the cppcms
comet application as a proxy between server and webclient?

Kind regards,
Eric

Hi! Artyom,

It's very nice to know CppCMS is under active development :-)

I have just switched to application_specific_pool and have not
encountered any issue with this new API *during last 10 minutes* :-)

Meanwhile, I want to take this chance to show off my modifications to my
local version of rpc_json.cpp as follows:

* Comment out line 162:   BOOSTER_DEBUG("cppcms") << "JSON-RPC Method
  call:" << method();

* Change line 181 from   return_error("Invalid parameters");   to
  return_error("Invalid parameters passed to JSON RPC method
  \""+method()+"\"");

* Change line 191 from   return_error("Internal Service Error");   to
  return_error("Invalid JSON RPC method: "+method());

CppCMS rocks! Simply can not find a single reason not using this superb
product and learning much C++ skills from it.

Happy new year! CN

For information: Last email I sent to you Artyom was about your emails

before I think).
You should be able to find that email again if you didn't delete it, I

Re: [Cppcms-users] E-Mails Missing

[Василий Т. <par...@gm...>]

Helo, Artyom.
Unfortunately (or, better, fortunately), I can't reproduce my previous
troubles with pid file overwriting.
May be, that was my mistake, and the pid file was replaced by init script
while created by the daemon.
Anyway, pid file creation after setuid is not convinient for me. I would
stay with systemd if you dont mind :)
Current systemd config ("daemon" section is absent in cppcms config):
------------------
[Unit]
Description=Lightning app server
After=network.target

[Service]
ExecStart=/opt/lightning/lightning
Type=simple
ExecReload=/bin/kill -HUP $MAINPID
ExecStop=/bin/kill $MAINPID
Restart=on-abnormal
User=www-data

[Install]
WantedBy=multi-user.target
------------------
Thanks for support!

No the connection will be created but when on attempt to recycle it into
the pool the "full pool" will be detected and the connection will be deleted.

i.e. @pool_size=3 means that no more than 3 connections are kept for
reuse.

[Cppcms-users] @pool_size passed to cppdb::connection

[CN <cn...@fa...>]

Hi!

Suppose each synchronous application establishes exact one
cppdb::connection passed with @pool_size=3. Imagine now there are 3
synchronous applications concurrently running in 3 threads.

What will happen if a synchronous application is launched to run as the
4th thread? Will it be blocked at

cppdb::connection myconn("...@pool_size=3...")

until some other thread finished its use of cppdb::connection, or the
4th instance of cppdb::connection will be created by the 4th thread
regardless of the "limit" imposed by the parameter @pool_size=3?

Thank you in advance for the clarification!

Best Reagards,
CN

Hi Artyom,

Great news for the new year which will begin.
I will try it and will give you a feedback if I have some problem or remark.
I'm able to receive your mail in my reception box now.
I suppose the problem is solved.

Thank you.

[Cppcms-users] CppCMS 1.1 - Progress Report

[Artyom B. <art...@gm...>]

Hello Dear CppCMS  Users,

If someone getting this as duplicate my apologize.
(Apparently GMail does not like my Yahoo mail sent via mailman :-)  )

--------------------

I'm getting ready to release next CppCMS beta version 1.1 (that would
become stable as 1.2)

Some preview of the work that was done so far:

  http://cppcms.com/wikipp/en/page/cppcms_1_2_whats_new

In the nutshell

- Redesigned applications pool and its API.
- New non-blocking I/O mode for asynchronous applications.
- On-the-fly uploads/post content processing support.
- Independent of context use of cache and session interfaces
- Support of non-cookies based session handling
- Integration of session handling with 3rd part technologies:
  PHP, Java Servlet, Aps.Net and so on and contributed modules.
  http://blog.cppcms.com/post/117
- Major performance and memory use improvements.
- Headers and Source separation by templates compiler.
  (Special thanks to Lee Elenbaas for the major contribution)

There are still few relatively small tasks in the TODO list before
beta will be officially ready.

  http://cppcms.com/wikipp/en/page/cppcms_1x_tasks#CppCMS.1.1.0.-.Next.Release

More than that  I'm changing the release policy to something that I
should do for a looooong time ago:

  --- release early, release often ---

CppCMS 1.1 was for too long in development and it isn't good...

I want you guys to looking on it:

- Try to build the version from trunk
- Try new API and report your impressions.
- Ask questions.

If some API issues are discovered I can make API changes before 1.2 is out.
However once 1.2 is released... the API will be frozen.

Thank You Very Much.

I'm expecting feedback.

Re: [Cppcms-users] E-Mails Missing

[Artyom B. <art...@gm...>]

Thank you a lot it allowed me to pinpoint the issue:

In short Yahoo does not recognize mails forwarded by mailman [1].
Something called DMARC
Mailman starting from 2.1.16 should support it. Unfortunately
Sourceforge's mailman version is
2.1.9 - basically this means GMail is going to scrap mails sent by
Yahoo via the list.

So until this stuff is going to be fixed I'll access this mailing list
via GMail.

I meant all the code, config files including systemd configuration and
sample app. If you can reproduce it on 'hello world' example.

Beilis, most of your messages go in the gmail spam folder with the error:

"It has a from address in yahoo.com but has failed yahoo.com's

Perhaps is a problem in your side?

Re: [Cppcms-users] E-Mails Missing

[Василий Т. <par...@gm...>]

step by step:
1) use daemon config with fork, setuid and pid file
On second start the daemon replaces its old pid file, finds the socket
being busy and exits. Thus we got healthy daemon and incorrect pid file.
2) put pid file handling inside init script:
PID=`$DAEMON $DAEMONOPT...  ans so on
The daemon unable to setuid by itself.
Direct call without ` lets the daemon setuid successfully, but i can't
handle pid file again.
3) simplest systemd config resolves all the problems, the daemon starts as
regular application.
Unfortunately, everything is at work - i can't get configs right now (very
typical ones).

Same here, we actually told you weeks ago...
gmail checks the address, see that is from yahoo but it fails some
